Detailed Description

Bridge between QwtSeriesStore and QwtPlotSeriesItem.

QwtAbstractSeriesStore is an abstract interface only to make it possible to isolate the template based methods (QwtSeriesStore) from the regular methods (QwtPlotSeriesItem) to make it possible to derive from QwtPlotSeriesItem without any hassle with templates.
